DOWNLOAD EBOOKUltra wideband (UWB) has advanced and merged as a technology, and many more people are aware of the potential for this exciting technology. The current UWB field is changing rapidly with new techniques and ideas where several issues are involved in developing the systems. Among UWB system design, the UWB RF transceiver and UWB antenna are the key components. Recently, a considerable amount of researches has been devoted to the development of the UWB RF transceiver and antenna for its enabling high data transmission rates and low power consumption. Our book attempts to present current and emerging trends in-research and development of UWB systems as well as future expectations.

DOWNLOAD EBOOKUltra wideband (UWB) communication systems are characterized by high data rates, low cost, multipath immunity, and low power transmission. In 2002, the Federal Communication Commission (FCC) legalized low power UWB emission between 3.1 GHz and 10.6 GHz for indoor communication devices stimulating rapid development of UWB technologies and applications. The proposed book Novel Applications of the UWB Technologies consists of 5 parts and 20 chapters concerning the general problems of UWB communication systems, and novel UWB applications in personal area networks (PANs), medicine, radars and localization systems. The book will be interesting for engineers and researchers occupied in the field of UWB technology.

DOWNLOAD EBOOKUltra wideband (UWB) communication is based on the transmission of short pulses on the order of nanoseconds. As a result, UWB systems operate over dedicated spectrum bands already occupied by other narrowband systems. Because a UWB device spreads its energy over a large frequency range, it radiates a small percentage of its total power in the operating spectrum of narrowband receivers. Consequently, UWB signals appear as low-power noise and have little impact on underlying operating devices. However, the interference coming from narrowband systems operating in the spectrum allotted for UWB use could be problematic. This thesis contains two main investigations. In the first investigation, we analyze the coexistence of time-hopping pulse amplitude modulation UWB systems in the presence of narrowband interference exploiting additive white Gaussian noise and flat-fading channels. The second investigation deals with the coexistence of UWB systems with narrowband interference based on experimentation.

DOWNLOAD EBOOKULTRA WIDEBAND WIRELESS COMMUNICATION AN INTERNATIONAL PANEL OF EXPERTS PROVIDE MAJOR RESEARCH ISSUES AND A SELF-CONTAINED, RAPID INTRODUCTION TO THE THEORY AND APPLICATION OF UWB This book delivers end-to-end coverage of recent advances in both the theory and practical design of ultra wideband (UWB) communication networks. Contributions offer a worldwide perspective on new and emerging applications, including WPAN, sensor and ad hoc networks, wireless telemetry, and telemedicine. The book explores issues related to the physical layer, medium access layer, and networking layer. Following an introductory chapter, the book explores three core areas: Analysis of physical layer and technology issues System design elements, including channel modeling, coexistence, and interference mitigation and control Review of MAC and network layer issues, up to the application Case studies present examples such as network and transceiver design, assisting the reader in understanding the application of theory to real-world tasks. Ultra Wideband Wireless Communication enables technical professionals, graduate students, engineers, scientists, and academic and professional researchers in mobile and wireless communications to become conversant with the latest theory and applications by offering a survey of all important topics in the field. It also serves as an advanced mathematical treatise; however, the book is organized to allow non-technical readers to bypass the mathematical treatments and still gain an excellent understanding of both theory and practice.

DOWNLOAD EBOOKThis Thesis focuses on an interference mitigation technique called Detect And Avoid (DAA), a terminology that was made popular by Ultrawideband technology. This report specifically addresses design and implementation challenges associated with DAA in the context of coexistence between UWB and WiMAX technologies. However the design problems, implementation issues and candidate solutions discussed herein are generic enough to be applicable to other radio architectures that use similar core building blocks, particularly for digital radio implementations that contain Fast Fourier Transform (FFT) engines. Another important aspect highlighted in this report is the impact of non-technical considerations such as regulatory requirements and cost implications on choice of certain approaches over others. Such considerations can be decisive from a hardware design perspective especially in low-cost, low-power consumer electronics market.
